Patent ES-344784-A1 (ES)
Title: Extrusion of Plastics Material.
IPC: B29C48/355
Filed: 1967-09-06
Abstract: A hollow extrudate of foamable plastics is extruded from an extrusion head 4, Fig. 12, comprising a mandrel 5 into a temperaturecontrolled sizing die 7 where expansion of the plastics takes place inwardly of the extrudate to fill or decrease in volume cavity 15b. The nature of the final product, i.e. whether hollow or solid, depends on various parameters, chief amongst which is the draw-off speed of caterpillars 80. Sizing die 7 may be electrically heated, or as shown, have fluid-flow chambers 9 the temperature of the die in any event is maintained below the gelling point of the plastics and a smooth non-cellular skin 13 is formed on the extrudate. Suction may be applied to the extrudate via apertures in the sizing die, see Fig. 5 (not reproduced), and also to the cavity in the extrudate via a conduit in the die head mandrel, see Fig. 4 (not reproduced). In the embodiment of Fig. 12, the draw-off speed of caterpillars 80 is varied to produce a product having alternate hollow and solid portions. Hollow bricks may be formed by cutting into lengths such a product when of rectangular cross-section. In the embodiment of Fig. 6, a tube having a bore of constant cross-section is obtained by using an extrusion head having two mandrels 44b, 45 and a sizing die 47 having a single mandrel 47b, the separate layers of plastics formed by mandrel 45 expanding in die 47 to fill the cavity therebetween. Other embodiments describe the formation of a product of T-cross-section, Figs. 4 and 5 (not shown), and of rectangular or biconcave cross-section, Figs. 9-11 (not shown). Inward expansion of the extrudate may be on to a solid core, e.g. an electrical conductor. Plastics specifically mentioned are polystyrene, styrene acrylonitrile copolymers, acrylonitrile-butadiene styrene copolymers, PVC and mixtures of PVC with acrylonitrile butadiene styrene, polymethylmethacrylate, polyamides, polyethylene, polypropylene, polycarbonate, cellulose propionate and polyurethane. Twenty one examples are given and these include descriptions of the production of longitudinally ribbed rods and rods where such ribbing has been smoothed to give the surface a fibrous appearance.

Title: Method and apparatus for filament winding planar structures
IPC: D04H3/04
Filed: 1967-09-12
Abstract: A non-woven sheet is made by passing an endless band 13 around spaced apart rollers, one of which is driven, applying filaments 55, to the top and bottom surfaces of the band in its lengthwise direction, helically winding other filaments 51 over the longitudinally extending filaments, applying to the filaments a heatcurable resin, at least partially curing the resin, e.g. at 31, removing the cured resin and filaments along the edges of the band, e.g. at 60, whereby the top and bottom lengths of sheets 89, 91 are separated, then removing the separate sheets from the band 13. The resin may be applied to the filaments after they are applied' to the band, e.g. at 59, or before the filaments are wound onto the band. A parting agent, e.g..polyvinyl chloride or polyvinyl alcohol, can be applied to band .13 to assist the release of the filaments and resin therefrom. The resin may be cured whilst it passes around' roller 17. The resin and filaments may be removed from the edges of the band 13 by passing it between vertical driven grinding rollers (61, 63), see Fig. 4 not shown. The metal band 13 may pass through a cleaning station prior to engaging roller 15. The filaments may be made of glass. The resin may be thermosetting.

Title: Process for preparation of ceramics of fissionable materials
IPC: C22C32/00
Filed: 1968-03-08
Abstract: Ceramics having open porosity are prepared from powders, particularly powders of fissionable materials such as oxides of U, Pu and Th, by compressing the powder at a pressure P to obtain granules which are then crushed and sifted and subjected to a second compression at pressure p (P p) to obtain a compact which is sintered, e.g. at between 1300-1700 C. In an embodiment, the starting material is a U0 2 powder with a specific surface area of 3-15 square metres/gm. and the pressure P is 5-9 metric tons/sq. cm. The granules made by the first compression are between 50-100 microns in diameter and are preferably subjected to a spheroidization process. The pressure p in the second phase is 2-5 metric tons/sq. cm. and the pressure difference P-p is suitably greater than 1 metric ton/sq. cm. The percentage of open porosity varies between 5-20% and the closed porosity between 2-3% of total volume. The product may be impregnated with a metal, alloy or a pyrocarbon to form a cermet (see Division B3).

Title: Oil burner system with motor-driven pump controlling bypass valve
IPC: H02K7/12
Filed: 1968-05-08
Abstract: Pumping apparatus for fuel-oil includes an A.C. induction motor having separate rotor parts 5, 8 coupled by shafts 6, 9 to an air-blower 7 and a rotary positive-displacement oil-pump 10, respectively, a valve (50), Fig. 2 (not shown), being opened by axial displacement of the part 8 and shaft 9 due to a compression spring 30 whenever the motor is switched off so as to reduce residual oil pressure in the pump. When the motor is switched on, movement of the part 8 and shaft 9 to close the valve is effected by forces tending to cause magnetic centring of said part, which may be facilitated by tapering the air gap between this part and the stator 1. The valve may be constituted by a portion 31 of the shaft 9 and a bearing bush 14. Excepting a region within a cup-shaped element 19, the interior of the motor is filled with oil.
